Struct darklua_core::LuaGenerator

pub struct LuaGenerator { /* fields omitted */ }

A struct to control how the Lua code is generated. Content can be pushed into the generator and it will automatically add spaces when necessary.

Implementations

impl LuaGenerator

pub fn new(column_span: usize) -> Self

Creates a generator that will wrap the code on a new line after the amount of characters given by the column_span argument.

pub fn push_str(&mut self, content: &str)

Appends a string to the current content of the LuaGenerator. A space may be added depending of the last character of the current content and the first character pushed.

pub fn push_char(&mut self, character: char)

Same as the push_str function, but for a single character.

pub fn merge_char(&mut self, character: char)

This function pushes a character into the string, without appending a new line or a space between the last pushed content.

pub fn into_string(self) -> String

Consumes the LuaGenerator and produce a String object.

pub fn for_each_and_between<T, F, G>(
    &mut self,
    vector: &Vec<T>,
    for_each: F,
    between: G
) where
    F: FnMut(&mut Self, &T),
    G: FnMut(&mut Self), 

A utility function to iterate on a vector and call the for_each function with each element of the vector and the between function between each element. It is useful when generating lists separated with a comma.

pub fn push_str_and_break_if<F>(&mut self, content: &str, predicate: F) where
    F: Fn(&str) -> bool, 

This function only insert a space or a new line if the given predicate returns true. In the other case, the string is added to the current generator content.

pub fn push_char_and_break_if<F>(&mut self, character: char, predicate: F) where
    F: Fn(&str) -> bool, 

This function only insert a space or a new line if the given predicate returns true. In the other case, the character is added to the current generator content.

Trait Implementations

impl Default for LuaGenerator

fn default() -> Self

Returns the "default value" for a type.
